textfield

问题 I have tested many ways to give the numeric and password constraint in the TextField. But its not working, See the below code. textField.setConstraint(TextField.NUMERIC | TextField.PASSWORD); textField.setInputModeOrder(new String[]{"123"}); Above code should work on the non touch mobiles. But its not working on the touch mobiles. So i have set the input mode value for VKB and bind that TextField with VKB , see this code. TextField txt = new TextField(); txt.setConstraint(TextField.NUMERIC

问题 I want to add validation in javafx TextField such that user should only be able to insert integer values ([0-9] and Dot ). Also user should be able to insert either B or b(for Billion) and K or k (for Thousand) and M or m( for Million). Basically it should be an amountfield. Delete and Backspace should also work. for example : 10k should become 10,000.00 as soon as user hit k and K should not be displayed on amountfield (textfield) Similarly 10M or 10m should convert into 10,000,000.00

问题 I want to compare two entries in a UITextField giving a number to each letter and then compare the results of the addition of the letters from both fields. Example: a=1 b=2 c=3 d=4 e=5 f=6 textfield1= cae textfield2= fca Result is: textfield1=9 and textfield2=10 回答1: You could use the unicode scalar representation of each character (look up ASCII tables) and sum these shifted by -96 (such that a -> 1 , b -> 2 and so on). In the following, upper case letters will generate the same number value

问题 I'm creating a formpanel with items created via xtype (not calling new for each items). I'd like to add a precision at the right of the TextField.

问题 I'm trying to move the caret in a Flex TextArea to the end after appending some text from my code. I've looked through the reference documentation for TextArea and its underlying TextField but it appears there is no method provided to handle this. One approach I've tried is to set focus to the text area and dispatch a KeyUp KeyboardEvent with the event's key code set to the "End" key, but this doesn't work. Any ideas on how to do this? Thanks. 回答1: Try this textArea.selectionBeginIndex =
